BEER-TAP.

SPECIFICATION forming part of Letters Patent No. 655,450, dated August '7, 1900. Application led June 23, 14898. Serial No. 684,221. (No model.)

To all whom, it Uta/y concern:

Beit known that I, JOHN MOHN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Beer-Taps, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to that class of beertaps particularly arranged and constructed for coupling it to a so-called tap-bushing, which is permanently secured to the head of the barrel or keg.

My invention is designed to form animprovement on the tap for which I have been granted Letters Patent No. 542,063, andthe improvement mainly relates to the peculiar construction of the sleeve of the tap, all as more fully hereinafter described, and set forth in the claims.

In the drawings, Figure l is a vertical central section through my improved tap and through the tap-bushing with which it is adapted to be coupled. Fig. 2 is a detached perspective view of the lower end of the sleeve of the tap. Fig. 3 is a horizontal section on line a: 00, Fig. l.

A is the sleeve or casing of the tap. B is the tap-tube, passing centrally through this sleeve.

C is a stuffing-box for the tap-tube, formed in the upper end of the sleeve.

D is an enlargement formed at the lower end of the casing and terminating in an annular shoulder or seat E.

F is a nipple on the lower end of the casing, preferably formed integrally with the sleeve or by securing a short piece of thin tubing into the lower end of the sleeve.

G is an air-inlet into the interior of the casing, provided at its inner end with the checkvalve H and at its free end with a suitable nipple L to connect thereto a rubber tube.

J is a coupling-sleeve formed at its lower end with an interiorly-projecting annular ange d and with coupling-lugs b, projecting inwardly from said iange at diametricallyopposite points.

c are inwardly-projecting lugs in the upper end of the coupling-sleeve engaging into longitudinal guide-grooves CZ, formed on the enlarged portion of the sleeve.

K is an adj usting-nut loosely engaging into an annular groove e on the sleeve and providedwith interior screw-threads f, engaging Awith the screw-'threaded upper end of the coupling-sleeve. The nut is made iu halves secured together by rivets g through wings h, formed on the nut.

L is a packing inclosed in the couplingsleeve around the nipple F.

M is the bushing, provided at one end with a screw-nipple lo, by means of which it is permanently secured in the head of the barrel,

and with a coupling-nipple Z, which has two` interrupted screw-flanges m m for the purpose of coupling thereto the tap. The bushing has a central bore substantially corresponding to that of the sleeve of the tap at its lower end, suitably enlarged to receive the nipple F, and an'annular flange fn forms the seat for the bushing in the head of the barrel.

The tap-tube is of smaller diameter than the interior bore of the sleeve and bushing, so that when the tap-tube is pushed inwardly into the barrel an air-space will be formed around the tap-tube, which is in communication with the air-passage G, and by reason of the construction described this airspace cannot become accidentally closed by the packing, as in my former constructiomwhere it is liable to close around the tap-tube when compressed between the tap and bushing. Other advantages are that in the present construction the packing may be of a size to fit the space in the coupling-sleeve and bind around the nipple, and it cannot be removed unless the coupling-sleeve is taken off. This prevents the accidental loss of the packing, which is such a troublesome feature in other couplings of this character. The nipple F also forms a guide and centering device in making the coupling.

What I claim as my invention isn l. The combination of a bushing secured in the barrel having a flanged coupling-nipple provided with a central bore and a coupling-seat around thermouthof the/bore, a sleeve or casing adapted to be coupled with said nipple and having at its lower end a tu- IOC bular extension adapted to fit into the mouth of the bore of the coupling-nipple and forming at its base a shoulder adapted to seat the casing upon the coupling-nipple, and a packing-rin g upon said tubular extension and having its seat upon the shoulder of the casing, said tubular extension projecting beyond the packing-ring to form a centerngguide in coupling and terminating in a thin edge adapted to be forced into the mouth of the coupling-nipple between the inner wall thereof and the cork.

2. The combination of a bushing secured in the barrel, having a Ilan ged coupling-nipple provided with an enlarged central bore, a sleeve or casing formed with a seat at its lower end adapted to be coupled to said nipple, a tap-tube slidingly secured within said casing,

the inner wall of the coupling-sleeve, said nipple having a thin lower edge adapted to enter the mouth of the bushing around the A cork therein.

In testimony whereof I aiix .my signature in presence of two witnesses.
